Chemical Structure
Description
The molecular framework of 5-(2,4-Dichlorophenyl)furan-2-carboxylic acid (C11H6Cl2O3) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
5-(2,4-Dichlorophenyl)furan-2-carboxylic acid (CAS 134448-46-7) is a high-purity analytical reference standard with the molecular formula C11H6Cl2O3 and a molecular weight of 257.07 g/mol.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO manufactures 5-(2,4-Dichlorophenyl)furan-2-carboxylic acid under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
